Good Morning Ashley,
Hunter, Jumper and Obstacle don't have preliminary classes (Jr Championship or Sr. Championship) or a Grand Championship class. Your horses just gather the 70 points total. Once you obtain your 70 points I would write a note to the ASPC/AMHR Registry addressed to the Show Department letting them know you have obtained your 70 points. They will check your horse's show record to be sure and then set up your Hall of Fame Award. Sometimes they will mail those awards out before Convention. If you want to have it presented to you at Convention, then take your award with you and ask that they give it out during the Hall of Fame Breakfast on Saturday morning.
The only performance classes that have a Stakes Championship are your driving classes. I know of a few driving class that doesn't have a Stakes Championship: AMHR Single Draft Harness, 2 Horse Draft Harness, 4 Horse Draft Harness, the 6 Horse Draft Harness and the Roman Chariot classes.
In the Halter division it's a bit different. You gather points in your Open Class, your Jr. or Sr. Championship Class and then your Grand Championship Class. In the Grand Class you MUST have competition (at least one other horse in the class) in order to get your Hall of Fame points in the Grand Class. If no other competition then your Grand Championship class doesn't count. You have to have 70 points and 5 Grand Championships. Your horse may obtain all 5 Grands as a weanling, or Yearling, but they MUST also win one as a two year old or older.
There are NO Hall of Fame points given for Model, Amateur, Color or any other classes that are not preliminary for champsionships.
This is a brief summary for you.
